Many normal situations involve calling people you do not know: a buyer for your old sofa, a potential landlord, a recruiter, a date. WhatsApp makes that easy. A few habits keep those calls from becoming a risk.

Before you share your number

Consider staying on the original app or platform until you trust the person.
Limit what strangers see on your profile. See privacy settings.
For selling or dating, a separate number can keep your main one private.

During the call

Keep your camera off unless it is needed, and check what is visible behind you.
Assume the call could be recorded. See what others can capture.
Never share codes, passwords or banking details.
Never share your screen. See screen sharing scams.
Never undress or act intimately. See video call blackmail.

You set the boundaries. A genuine buyer, landlord or recruiter will respect you saying "let's keep it to messages" or "I'll call you back on the agency's number".

After the call

Block and report if anything felt wrong.
Verify business claims independently before paying anything. See verifying payment requests.
